Flag metaphor

For Poetry Month 2014,
I’m searching for metaphors and similes.
Join me!  Here’s a bit more on this month’s project.

I’m thinking about my nephew.  It’s his birthday.

What’s a metaphor for this radiant young man?

A star?  A fresh-picked grape, bursting with flavor?  The peal of a bell?

Or perhaps a crisp flag, snapping in the wind?

I’m playing around with this metaphor in a rough draft:

BIRTHDAY BOY

You are a flag in the wind
beaming your colors
on this blustery day

Join me–what’s your metaphor today?
